I already have another deck to play =/
Nerfs are not a problem.
For someone who actually DOESN'T play the game, it might be difficult to get cards, but for a player is kinda easy to farm.
I already beat blue-eyes deck blindfolded, and many of my friends are doing so as well.
Everybody can beat a new Brick Eye deck, as even with Arkana a cosmo brain isn't much good if it has nothing to summon itself with.
Nearly every deck can beat nearly every deck, the heart of the brick is with everybody. Cyberdark is pretty awesome IF you have a BEUD or Five Headed dragon knocking around, which I don't as those reside within garbage cans.
